Abstract

This chapter provides a selective survey of recent developments in the study of social welfare under oligopoly. The main topics covered are (i) the rate of cost pass-through as a tool to analyze market performance; (ii) the quantification of welfare losses due to market power in Cournot-style models; and (iii) new results from models with endogenous entry. The chapter highlights common themes across these topics and identifies areas for future research.
